I bought a three pack so I could place around the house. The first two I open worked perfectly, but the third did not work. I emailed the company and they got back to me within hours and sent me a replacement within a couple days. I’m extremely impressed with our customer service and I will lookto buy other items from this company in the future.

We sold the house and we’re required to put in carbon monoxide detectors. This is the best way to go. They’re inexpensive. They meet the requirements for having carbon monoxide detectors in a house and you can plug them into any of the rooms you need to they can be moved around and when you test them, they work really well and it actually works to tell you, the levels in your room need these ever again this is the way I would go. They were easy to plug-in and the value is great.
